A film'of liquidbrought into con tact with a heated surface as" of aradiator pipe is quickly vaporized. Vapor thus produced and sists in the association of porous sheet materialwith laterally spaced' pipes, said material being applied in direct contact with'the pipesand in a manner to form a passageway which -is open at both ends and through which the pipes'extendso that space between the pipesprovides a'fiue for a free currentof ainiand means 'for supply ing liquid to the porous material. Advantages of the simple structure comprising the invention are fully set forth in the following detailed de scriptionin which reference is 'made to 'the' 'a'c-f companying drawings wherein'as illustrated-one convenient form of embodiment-of the invention} In the drawings,-

Any-j-suitablearrangement may be provided for conducting'and distributing water to the fabric tube -8.-='-As"shown a plate -15 of metal or'oth'er I suitable material is placed upon the top of radiato'risections 'ofwhich the conduits are surroundedby tube BffOverlyin'g this plate is the central portion of: a wick 16 from which extend any desired number of leaders'lfl' which maybe fastened at their-extremities to tube 8 as=by stitchingj ""WaterZ for delivery to wick .16 may be contained in an adjacent tank or as shown a supply'pipe 'l'il maybe provided and fitted with a regula'table drip cook 19;" y Forenclosing the entire radiator .a casing may be provided or if preferablecertain'sectionsjonly maybe covered including those to which the liq uid conducting porous material is applied. As

shown a casing encloses four sections including, one on i each side of those supporting the porous material. "This casing,*preferably of sheetmetal, may comprise a 'skirt portion 20, panels 21' and 22 anda bottom closure or-drip pan23. 'The skirt portion 20 includes a perforated top 24 which may be integral or separate therefrom,

, Opposite sides of the casing skirt portion 20 are provided with openings as'25 and 26 to receive respective panels 21 and 22V The edges of the openings and panels, designed to engage each other, are preferably formed to make tongue and groove joints so that whenthe panels are placed 2 r f f 7 1,995,409

in position between the transverse conduits 4 and 5 the skirt portion may be'placed thereabove and telescopically slipped into engagement with the panels. The upper end of each opening and 26 is formed to approximately fit the upper conduit 4 and the lower end of each panel 21 and 22 isformed to approximately fit the lower conduit 5 so that the casing when assembled on the radiator makes a flue substantially closed at the sides except for perforations ,27 which are provided near the bottom of the skirt to admit a current of air. When the skirt and panel portions of the casing have been assembled the drip pan 23 may be readily secured to the skirt as by screws 28. The ends of the drip pan are formed to fit around the lower conduit 5 and at one end of the pan there is connected thereto a drain pipe '29.

The functions promoted by the'describedstructure are performed as follows: Water from drip cock 19 falling upon wick 16 is conducted by the leaders from the latter to the .fabrictube 8. I Per-g meating the interstices of the fabric the water;

is spread over a large area and broughtbqth 'di- .rectly into.contact with .the heated surface ot conduits 3,and:in close proximity thereto, so that,

itis. quickly vaporizedflincomparatively large volume. .Coming into .conta'ctwith'the heated surface of the radiator, currentsof air are continuously induced within the tube 8 itself which forms a'flue betweenthe tubev enclosed pipes and within the casing whichforms a flue. surroundin the tube so that both theinnerand outer surface of the. saturated fabricare traversedbmthe air currents which directly takei'vapor whereitis. generated and impel it upward and out through perforations of the top 24.-and* thence into dif, fusion through the atmosphere. Any ,water in excess of'an amount which the fabric tube will support for vaporization passesdownwardly into Y drip pan' 23. P

In the modified 'form'of means (shownrin' Fig. 6). for conducting liquid, to porous material associated with the intermediate portionjof radi ator sections 31 and 32, thereisprovided for each a section a hood as 33, also of porous material, close I ly fitting over the top ofits respective; section.

plate 34 is supported over these hoodsand oV er. lying the plate is a wick 35 having the shortleaders as 36 by which liquid iscarried to the hoods and distributed thereover to saturate. the entire hood as well as the tube adjoined thereto below;
